Chemical Mixing Tank Design – Important Considerations
There are many factors to consider when designing a chemical mixing tank. This article will discuss some of the most important things to keep in mind. When designing a chemical mixing tank, there are many factors to consider. This article will discuss some of the most important things to keep in mind. The first factor to consider is the type of material that the tank will be made from. The type of material will affect the tank's durability, chemical resistance, and overall cost. The next factor to consider is the tank's size. The tank's size will determine the number of chemicals that can be mixed in it.
The structure of the mixing tank is mainly composed of the stainless steel tank, stirring device, transmission device, accessories, shaft sealing device, and other parts. The stainless steel mixing tank is designed according to the requirements of the production process structure, and the configuration can be standardized and humanized.
Mixing tank body part: stainless steel tank body is composed of the cylinder and the upper and lower head; the general structure is sealed and can also be designed according to the process into an open type. The mixing tank body and cover can also be opened according to the process requirements of feeding, discharging, observation, temperature measurement, pressure measurement, steam fractionation, safety venting, and other process pipe holes. The tank body is generally made of 304/316L stainless steel according to the different process requirements.
The stirring device of the tank: The stirring device is composed of a moving shaft and stirrer. Due to the different production processes of each customer, the stirrer can be configured in various forms, such as slurry, anchor, frame, and spiral, according to additional process requirements. The agitator can also be installed according to different mixing requirements. The agitator is usually inserted vertically into the tank from the top center of the mixing tank, and there are also side insertion and bottom insertion methods.
The transmission device of the mixing tank: the transmission device includes the motor, transmission, coupling, bearing, frame, etc. Among them, the stirring drive usually uses a combination of engine and transmission or chooses the motor with a frequency converter so that the moving to achieve the required speed. The role of the transmission device of the mixing tank is to make the necessary rotation speed of the emotional shaft.
Accessories of mixing tank: The mixing tank can be equipped with a maintenance hole, hand hole, pressure gauge, receivers, thermometer, sight glass, safety valve, and other accessories according to the production process requirements.
Shaft sealing device of mixing tank: The shaft sealing device usually used on the mixing tank mainly has two forms: packing seal and mechanical seal. Among them are two types of mechanical seals: single-end mechanical seals and double-end mechanical seals. These forms can be selected according to the customer's production needs for different sealing devices.
